Copeland Comfort Control (Alco) 064289 Expansion Valve

The Copeland Comfort Control (Alco) 064289 Expansion Valve is a balanced ported valve engineered for precision refrigerant metering in commercial refrigeration and low-temperature applications. Utilizing a stainless steel replaceable power element, this 1-ton capacity TXV is built to resist corrosion and ensure long-term reliability in harsh environments. The Model HFES 1 SZ 5FT features an externally equalized design with a straight body configuration and 3/8" x 1/2" ODF sweat connections, making it a drop-in solution for contractors servicing systems using R404A, R507, or R502. Designed with a low temperature charge (SZ) and a 5-foot capillary tube, this thermostatic expansion valve maintains stable superheat even during fluctuating load conditions. Whether you are performing a TXV replacement or a new system install, the HFE series expansion valve provides the bi-directional capability required for versatile heat pump and refrigeration setups, ensuring optimal evaporator efficiency and compressor protection.

• Balanced Port Design: Compensates for changes in head pressure, ensuring consistent superheat control across varying ambient temperatures.
• High Durability: Equipped with a stainless steel power assembly to prevent common failure points caused by atmospheric corrosion.
• Multi-Refrigerant Compatibility: Optimally tuned for R404A/R507/R502 systems, providing a 1-ton nominal rating for low-temp reach-ins and walk-coolers.
• Flexible Installation: Features ODF sweat connections and a 5' capillary tube to accommodate complex piping layouts and remote bulb placement.
• External Equalization: Essential for systems with significant pressure drops across the evaporator, ensuring accurate bulb response.

• What is the benefit of the SZ low temperature charge? The SZ charge is specifically formulated to provide rapid response and stable control in low-temp applications, preventing hunting and evaporator freeze-ups.
• Can this valve be used in bi-flow applications? Yes, the HFES series is designed with bi-directional capability, making it suitable for both refrigeration and heat pump cycles.
• How do I verify if the power element is failing? If the system exhibits high superheat that cannot be adjusted or if the valve remains starved despite a correct refrigerant charge, the stainless steel power element may need inspection or replacement.
